I knocked up this short video, it shows amsteel dyneema 11mm 12 strand, being subjected to 300c and 600c via a heat gun.

 

As you can see there is hardly any change at 300c.

so you pointed a glorified hair dryer at a piece of rope, what does that prove:confused1: its not really being subjected to the forces involded in rigging is it

Its a heat gun, like a paint stripping one, to prove that heat at a higher degree than friction does little damage - unless you can tell me the temp friction is?

 

 

You have not used dyneema, I have and dropped heavy blocks with no change to the sling in anyway.

I thought it was only me thinking...I don't rig with a hot air gun :confused1:

 

:biggrin:

 

your a good splicer, would love to see your reaction to using Dyneema.

That was my spider leg. It was inch amsteel running on 19mm dynasorb. I was using them on a big cypress dismantle, everything was getting rigged off big. The spider legs were being used to balance limbs to take everything in one.

 

Everything seemed to balance nicely but after I took the largest limb off, the amsteel prusic had to be peeled off the dinasorb.

 

No significant slippage occurred because the limb balanced nicely but even so what little did occur damaged the spider leg.

 

I had thought amsteel would be fine in this application because of the nature of balancing. I still feel it would be good for this if using something else to adjust the spider leg.

so did just a small area seal itself to the dinasorb?

 

because dyneema has amazing heat absorption, deflecting the friction heat, was it just a small amount?

No i have seen dans amsteel blue spiderleg and its not a small area considering it melted to the rope i think that shows it doesn't deal with heat very well

its not resistant to heat, but it absorbs it and slows the progress, thats why its in bulletproof vests, motorcycle jeans and chainsaw trousers.
